Shareholding notification

With reference to the law and grand ducal regulation of 11 January 2008 on transparency requirements for issuers of securities, the shareholding notifications are made available below:

Share buy-back authorization

The general meeting of shareholders decided on 13 June 2020 to cancel the authorisation granted by it to the board of directors on 5 May 2015 with respect to the share buy-back programme, and to authorise the board of directors, with option to delegate, and the corporate bodies of the other companies in the ArcelorMittal group, to acquire and sell shares in the Company during a period of five years or until the date of its renewal by a resolution of the general meeting of shareholders if such renewal date is prior to the expiration the five-year period, in accordance with Luxembourg law of 10 August 1915 on commercial companies, as amended (the “Law”).

It includes the authorisation to enter into off-market and over-the-counter transactions and acquire shares in ArcelorMittal through derivative financial instruments.

The maximum number of shares that may be acquired is the maximum allowed by the Law in such manner that the accounting par value of the Company’s shares held by the Company do not in any event exceed 10% of the Company’s issued share capital.

The maximum number of own shares that ArcelorMittal may hold at any time directly or indirectly may not have the effect of reducing its net assets ("actif net") below the amount mentioned in paragraphs 1 and 2 of Article 461-2 of the Law.

The purchase price per share to be paid shall not exceed 110% of the average of the final listing prices of the 30 trading days preceding the three trading days prior to each date of repurchase, and shall not be less than one euro cent. The final listing prices are those on the Euronext markets where the Company is listed or the Luxembourg Stock Exchange, depending on the market on which the purchases are made.

For off-market transactions, the maximum purchase price shall be 110% of the reference price on the Euronext markets where ArcelorMittal is listed. The reference price will be deemed to be the average of the final listing prices per share on these markets during thirty (30) consecutive days on which these markets are open for trading preceding the three trading days prior to the date of purchase. In the event of a share capital increase by incorporation of reserves or issue premiums and the free allotment of shares as well as in the event of the division or regrouping of the shares, the purchase price indicated above shall be adjusted by a multiplying coefficient equal to the ratio between the number of shares comprising the issued share capital prior to the transaction and such number following the transaction.
